It happened on Tuesday in the Southern California desert, but her boyfriend, David Lucado, shouldn't freak. The "Toxic" singer was locking lips with the grunge-looking hunk for a new video clip for "Perfume," a track from her eighth album, Britney Jeanalbum, which is due Dec. 3.

Britney herself was dressed down for the shoot, forgoing her usual glammed-up, sex-kitten clothing for jeans, boots and a white tank top shear enough to show her matching white bra. When things cooled down in the evening, both Spears and her mystery man donned leather jackets, according to US Weekly.

The clip is being directed by Joseph Kahn, who lensed previous Brit vids for "Stronger" and "Toxic." Britney tweeted about the collaboration:

So stoked to be working w/@JosephKahn again. We've had a lot of success together & there is nobody I trust more w/this super personal song.

If the mystery man looks younger than the 31-year-old Spears, it's because he is. He's been identified as 28-year-old Norwegian model Alexander Kjellevik.

Spears has said that the song "Perfume" and the rest of the album is deeply personal. The song includes the lyrics, "And while wait I put on my perfume, yeah I want it all over you, I gotta mark my territory." That might make you think that Britney's like a rabid dog in heat, but have no fear, she's doing it all for the fans, she said in a tweet:

I made this album specifically for my diehard fans so I'm just hoping every song touches you because each one is a piece of me.
